DEVICE FOR CONTROLLING THE HEAT 0] INTERNAL-COMBUSTION MOTORS.

Application filed April 21, 1923. Serial No. 633,792.

To all whom it may concern:

Be it known that we, JOSEPH O". Foncn'r'rn and RICHARD LEGOIS, both citizens of the United States, and residents of Hartford, in the county of ashington and State of WIS- consin, have invented a new and useful Improvement in Devices for Controlling the Heat of Internal-Combustion Motors, of which the following is a full, clear, and exact description. I

Our invention relates to improvements in devices for controlling the heat of an internal combustion motor, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of our invention is to provide a device for controlling the heat of a motor which is manually controlled, and is adapted to be instantly set so as to keep the heat of the engine at the desired temperature.

A further object of our invention is to provide a device of the type described which accurately controls the temperature of the engine, whereby devices for controlling the flow of air into the radiator, such as a card board placed in the front of the radiator, are done away with.

A further object of our invention is to provide a device of the type described which is adapted to prevent air from passing over the motor when the car is moving, whereby the heat of the motor will not be dissipated.

A further object of our invention is to provide a device of the type described which can be readily attached to an ordinary automobile engine, and which is adapted to take the place of the fan that is normally used for cooling the radiator.

A further object of our invention is to provide a device of the type described which is simple in construction, durable and efficient for the purpose intended, and which is not likely to easily get out of order.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

Our invention is illustrated in the accompanying drawings forming part of this application, in which-- Figure 1 is a vertical section through the device, portions thereof being shown in elevation, and

Figure 2 is a front elevation of the device.

In carrying out our invention, we make use of an engine 1 which has a crank shaft 2 and a fan carrying shaft 3. We apply the device to the shaft 3, the device taking the place of the fan the shaft. The device consists of a pulley 4. which is mounted upon a hub 5 that is retatably carried by the shaft 3. Thrust bearings 6 take up the end play of the pulley 4. The crank shaft 2 has a pulley 7 which is operatively connected to the pulley 4 by means of a belths. .Itwill bef-no'ted from this construction that whenfl. th'e engine is running, it will rotate the pulley 42f.

The pulley 4 carries -pr" which have their{ shafts posed on the pulley.

pellerblades A lo rotatably'f dis- The pulle'y ines; a recess 11 into which the inner' ends ofthe' shafts 10 project. The blades "9-f'willfbe swung when the, shafts "10 .are: rocked. The

means for rocking the sh'afts'10 consists of arms 12, which are readily secured to the shafts 10 that have their free ends operatively connected to a ring 13. The ring 13 is provided with slots 14, into which the free ends 15 of the arms 12 are slidably disposed.

Movement of the ring will cause the arms 12 to swing the blades 9. The means for moving the ring 13 consists of a grooved ring 16 that is slidably mounted upon the shaft 3. The ring 16 is connected to the ring 13 by means of rods 17, which in turn are slidably disposed in bores 18 of the pulley 4. A yoke 19 is operatively connected to a manually controlled lever (not shown) by means of a link 22. Movement of the link 22 will cause the ring 13 to move so as to swing the blades 9. The rings 13 and 16 and the rods 17 are rotated with the pulley 4.

The blades 9 are held in any desired position by means of spring pressed lungers 23, which are slidably disposed in ores 24 of the pulley 4. The rods 17 are serrated at 25 and the ends of the plungerswhich enga e with the rods are wedge-shaped, where y the plunger prevents normal movement of the rods 17 in the bores 18. The lungers 23, however, will yield when the rods 17 may be moved at will so as to swing the plates 9. The springs 26 which bear against the plungers 23 are held in place by means of screw plugs 27.

It will be noted from Figure 2 that each of the blades 9 is pivotally secured at each end. The inner ends of the blades 9 are pivotally held in place by means of the which is usually carried by ink 22 is manually actuated, whereby the shafts 10, while the outer ends of the blades are provided with trunnions 28, which are rotatably disposed in sockets 29 of the ring 30.

From: the foregoing description of the various parts of-thedevice, the operation thereof may be readily understood. As heretofore stated, the device can be readily applied to the fan-shaft 3 of the automobile and takes the place of the ordinary engine cooling fan.

Assume that it is winter time, and that the water in the radiator has become frozen. The operator can adjust the lever22 so as to swing the blades into a position which will prevent air from being drawn through the radiator. The engine will soon become h heated when started, and will retain practically all of its heat, since the blades 9 are not forcing air over the engine so as to cool the latter. The heated engine will uickly melt the ice in the radiator, where y the circulation of water is once morestarted. In winter travel, it is often necessary for the operator to place a cardboard over the front of the radiator,'or have some device for preventing the air from entering the radiator, during the time the car is running. In the present device, the blades can be swung so as to prevent an from passing into the radiator, whereby the engine will not be cooled to such a degree as to prevent the engine from operating efficiently. If desired, the blades can be swung so as to force the air from the engine out through the radiator. This. flexibility of control permits the driver to keep t e heat of the enine at any degree of temperature desired.

he device is simple in construction, and can be readily attached to the fan shaft of an engine.

We claim:

1. A device of the type described comprising a housing adapted to be rotated, blades carried by said housing, said blades being adapted to rotate on their longitudinal axes, means for swinging said blades into any angle desired, means for locking said blades in adjusted sition, and means connecting the outer en s of said blades together.

2. A device of the type described comprising a shaft, a housing mounted on said shaft, a plurality of blades carried by said ousin means securing the outer ends of said b ades together, said blades being rotatably mounted in said housing and said means, rods slidably carried by said housing and being operatively connected to said blades, means for locking said rods in adjusted position, and common means for actuating said rods.

3. A motor fan comprising a shaft, a casing carried by said shaft, blades rotatably carried by said casing, arms secured to said blades, a ring having slots-therein, the end of said arms slidably received in said slots, means for moving said ring whereby said blades are rotated on their longitudinal axes and means for locking said blade swinging means and a ring secured to the free ends of said blades.
